Abstract

The present invention permits backup processing suited to data characteristics relating to backup target data by means of a method that is simple for the user. Data characteristic classification definition information, in which data characteristic IDs correspond with one or more data characteristic types respectively, and mapping information, in which backup destination server information corresponds with one or more data characteristic IDs respectively, are prepared. The backup source server 3 sets data characteristic IDs in each of the backup target files on the basis of metadata of designated backup target files and of the data characteristic classification definition information, and then determines backup destination servers 6A to 6C for each of the backup target files on the basis of the set data characteristic IDs and mapping information and transmits the backup target files to the determined servers 6A to 6C.

Claims

1. A backup system, comprising:

a backup source computer device that stores backup target data;

a plurality of backup destination computer devices each connected to the backup source computer device via a network;

a backup mode selector that selects, according to data characteristics of the backup target data, any one backup mode from among a plurality of pre-prepared backup modes; and

a backup executor that stores the backup target data by transferring the backup target data from the backup source computer device to a backup destination computer device that is selected on the basis of the selected backup mode from among the backup destination computer devices,

wherein the backup executer selects the backup data on the basis of a data characteristic classification definition information which is information relating to rules on how backup target data are classified.

2. The backup system according to claim 1, wherein the backup data is selected on the basis of at least one or more of judgment elements comprising the presence or absence of encryption, the number of common users, special features common to common users, the presence or absence of access restrictions, file extension type, file name, and the presence or absence of predetermined keywords.

3. A backup method that performs a backup between a backup source computer device for storing backup target data and a plurality of backup destination computer devices each connected to the backup source computer device via a network, the backup method comprising:

selecting, according to data characteristics of the backup target data, any one backup mode from among a plurality of pre-prepared backup modes;

selecting the backup data on the basis of a data characteristic classification definition information which is information relating to rules on how backup target data are classified; and

storing the backup target data by transferring the backup target data from the backup source computer device to a backup destination computer device that is selected on the basis of the selected backup mode from among the backup destination computer devices.
